From 2c645b61cc37922b6453d31a832c4ff24ef8c465 Mon Sep 17 00:00:00 2001 From: Renaud Gaspard Date: Sun, 22 Jan 2023 20:41:48 +0100 Subject: [PATCH] ramips: Add support for TP-Link Archer C50 v6 (CA/EU/RU) This adds support for the TP-Link Archer C50 v6 (CA/EU/RU). (The ES variant is a rebranded Archer C54 and NOT supported.) CPU: MediaTek MT7628 (580MHz) RAM: 64M DDR2 FLASH: 8M SPI WiFi: 2.4GHz 2x2 MT7628 b/g/n integrated WiFi: 5GHz 2x2 MT7613 a/n/ac ETH: 1x WAN 4x LAN LED: Power, WiFi2, WiFi5, LAN, WAN, WPS BTN: WPS/WiFi, RESET UART: Near ETH ports, 115200 8n1, TP-Link pinout Known issues ------------ - Enabling 5GHz WiFi may crash the system. Workaround: restart the box, 5GHz WiFi works properly afterwards. Create Factory image -------------------- As all installation methods require a U-Boot to be integrated into the image (and we do not ship one with the image). We are not able to create an image in the OpenWRT build-process. Download a TP-Link image for your device variant (CA/EU or RU) from their website and a OpenWRT sysupgrade image for the device and build yourself a factory image like following: TP-Link image: tpl.bin OpenWRT sysupgrade image: owrt.bin > dd if=tpl.bin of=boot.bin bs=131584 count=1 > cat owrt.bin >> boot.bin Installing via Web-UI --------------------- Upload the boot.bin via TP-Links firmware upgrade tool in the web-interface. Installing via Recovery ----------------------- Activate Web-Recovery by beginning the upgrade Process with a Firmware-Image from TP-Link. After starting the Firmware Upgrade, wait ~3 seconds (When update status is switching to 0%), then disconnect the power supply from the device. Upgrade flag (which activates Web-Recovery) is written before the OS-image is touched and removed after write is succesfull, so this procedure should be safe. Plug the power back in. It will come up in Recovery-Mode on 192.168.0.1. When active, all LEDs but the WPS LED are off. Remeber to assign yourself a static IP-address as DHCP is not active in this mode. The boot.bin can now be uploaded and flashed using the web-recovery. Installing via TFTP ------------------- Prepare an image like following (Filenames from factory image steps apply here) > dd if=/dev/zero of=tp_recovery.bin bs=196608 count=1 > dd if=tpl.bin of=tmp.bin bs=131584 count=1 > dd if=tmp.bin of=boot.bin bs=512 skip=1 > cat boot.bin >> tp_recovery.bin > cat owrt.bin >> tp_recovery.bin Place tp_recovery.bin in root directory of TFTP server and listen on 192.168.0.66/24. Connect router LAN ports with your computer and power up the router while pressing the reset button. The router will download the image via tftp and after ~1 Minute reboot into OpenWRT. U-Boot CLI ---------- U-Boot CLI can be activated by holding down '4' on bootup. Dual U-Boot ----------- This is the first TP-Link MediaTek device to feature a split-uboot design. The first (factory-uboot) provides recovery via TFTP and HTTP, jumping straight into the second (firmware-uboot) if no recovery needs to be performed. The firmware-uboot unpacks and executed the kernel. Web-Recovery ------------ TP-Link integrated a new Web-Recovery like the one on the Archer C7v4 / TL-WR1043v5. Stock-firmware sets a flag in the "romfile" partition before beginning to write and removes it afterwards. If the router boots with this flag set, bootloader will automatically start Web-recovery and listens on 192.168.0.1. This way, the vendor-firmware or an OpenWRT factory image can be written. By doing the same while performing sysupgrade, we can take advantage of the Web-recovery in OpenWRT. It is important to note that Web-Recovery is only based on this flag. It can't detect e.g. a crashing kernel or other means. Once activated it won't boot the OS before a recovery action (either via TFTP or HTTP) is performed. This recovery-mode is indicated by an illuminated WPS-LED on boot.
